So says Larry Young, PhD, chief of the Division of Behavioral Neuroscience and Psychiatric Disorders at the Yerkes National Primate Research Center, Emory University.
Young, who is world-renowned for his work on the role of neuropeptides in regulating social behavior, uses voles to investigate the neurobiological and genetic mechanisms underlying social behavior. Using the monogamous prairie vole (vs. the promiscuous meadow vole) as a model organism, Young and his research team identified the oxytocin and vasopressin receptors as key mediators of social bonding and attachment. In addition, they are examining the consequences of social bond disruption as a model of social loss-induced depression.
This work has important implications for developing novel treatment strategies for psychiatric disorders associated with social cognitive deficits, including autism spectrum disorders and schizophrenia.
Exercise provides health benefits
Researchers at Emory University and the University of Georgia have received funding from the National Institutes of Health to study the neurobiological mechanisms for how regular aerobic exercise may prevent drug abuse relapse. The grant is for $1.9 million over the next five years.
David Weinshenker, PhD, associate professor of human genetics, Emory School of Medicine, is a co-principal investigator on the project.

â€œThis research will provide new insight into how regular exercise may attenuate drug abuse in humans,â€ Weinshenker says â€œMore importantly, it may reveal a neural mechanism through which exercise may prevent the relapse into drug-seeking behavior.â€
During the study, Weinshenker and UGA co-investigator Philip Holmes, professor of psychology in the Franklin College of Arts and Sciences, will measure exercise-induced increases of the galanin gene activity in the rat brain.
